Here are parts of the syslog at system boot for matroxfb and vesafb : matroxfb: Matrox Mystique (PCI) detected matroxfb: MTRR's turned on matroxfb: 640x480x8bpp (virtual: 640x13075) matroxfb: framebuffer at 0xE7000000, mapped to 0xc8805000, size 8388608 Console: switching to colour frame buffer device 80x30 fb0: MATROX VGA frame buffer device vesafb: framebuffer at 0xe7000000, mapped to 0xc8000000, size 8192k vesafb: mode is 640x480x8, linelength=640, pages=11 vesafb: protected mode interface info at c000:7820 vesafb: scrolling: redraw Console: switching to colour frame buffer device 80x30 fb0: VESA VGA frame buffer device After booting and having the display shifted to the middle of the screen, I've played a bit with fbset and the -left, -right, -move, -match options. After a while I got an 'acceptable' picture (some pixels missing on the left). At this point, fbset -s give me the following : mode "640x480-60" # D: 25.176 MHz, H: 31.628 kHz, V: 60.243 Hz geometry 640 480 640 480 8 timings 39721 50 10 32 11 96 2 accel true rgba 8/0,8/0,8/0,0/0 endmode I've replaced these values in /etc/fb.modes instead of the original values and after login in the system, entering 'fbset -match -a' set the virtual consoles correctly. How can I pass the parameters at boot time ? I've tried : video=matrox:vesa:0x301,pixclock:39721,left:50,right:10,upper:32,lower:11,hslen:96,vslen:2 ... without any success... -- Regards Jean-Luc - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
